Be it kno'wnthat I, CHARLES nmitnl.l BL'EBBING, of the city and countyof Philadelphia, and State of j .1

Pennsylvania, have invented a nexr and useful Improvement inCopper-Lined Bath-Tubs; and I do hereby declare that the following is afull and exact description thereof, reference being had totheaccompanying drawings, and to the letters of `reference marked thereon.`

'The nature of my invention will he `understood. bythe followingdescription.

In lthe accompanying draviings, whichform a part of thisspecicntion-Figure 1 is anisc'metrical view of the-improved tub.' Y

Figure 2 is a. cross-section of the same` Like letters in both thegure's indicate 'the same parts. r i I The usual mode of lining the tubsis to4 joint the lining iii the bottom, and consequentlyhe tubsfrequently4 leak, on account o-the loosening of the joints, caused bythespringing of the sides. of the tub. The joints, ivhich are usually inthe corners, 'are also loosened by the shrinking of 'the `wooden bottom,and also bythe weight of a, Aperson when stepping into the tub.

" WTQ obviate these diioultes, I Tine the" tubs without the bottomseams, making the 'main pantt''o1"tl1el lining of n lsinglepiece, B,'and soldering the end-pieces, C C, thereto, as represented in g. 1.Consequently the tendency to leakage, caused-by the springing of 'thesides, shrinkage of the bottom, die., is obviated. The` 4baths are alsomuch more durable than those of ordinary construction, effecting a greatsaving in the item of repairs, besides avoiding the trouble incidentalto leakages. The liningat the bottom of the tubs is also much smootherthan when ther t to the wood. v V v According to the present plan ofconstructing bathing-tubs, in order to furnish as secure a joint aspossible in 'the bottom of'the tub.,thick sheets of metal have ofnecessity been used'; andas hard metal, such as zinc and copper, is muchmore expensive than the softer metals, such as lead, the latter hasgradually grown into use, its cheapness alone recommending it.` Manyobjections to, the use of lead fcxbathing-tubs could readily beadvanced, such, for instance, as itsmore or lessgl'iability to corrode;and especially is it objectionable when used for hot bathsf'as the vaporthat vill ris@ no matteihow slight the same maynppear to be, is mostinjurious. When the tub is lined with copper, all these objections areentirely removed. There is corrodeslwhen subjected to the action ofnitric or other like acids.

According to my present plan, the seams inthe bottom being entirelydispensed with,'all danger of leaking no vapor 'or other unwholesomeinfluence, no matter how great the heat; and it is wellknown that copperonly is entirely removed, very thin sheets of metal can safely be used,and the .tub is therefore not only much more durable, but far lighterand much neater in appearance'.

Having thus fully described my invention, what I claim therein as new,and desire to secure by `Letters Patent of the United States, is l Abath-tub lining made of sheets of hard metal, such as copperor'zine,consisting of the`partsB CC, nhen the same are constructed and arrangedas described.

In testimony whereof, I have hereunto set my hand and aflixed my seal,this fourth day of March, 1867.
